Haikouichthys ercaicunensis was one of the earliest known vertebrates, living in what is now southwestern China during the Cambrian, around 518 million years ago.
About 2.5cm long (~1"), it had a streamlined body with a long fin along its back and tail. It lacked limbs and jaws, but it did have a flexible "upper lip" that could potentially have been used to manipulate food particles, either engulfing them on the seafloor or stirring them up into the water for filter-feeding.
And a recent study revealed a big surprise β it had four eyes! Along with its already-known large sideways-facing pair of eyes, it also had another smaller upwards-facing pair in the middle of its face, giving it a much wider field of vision and the ability to watch out for predators from multiple angles at once.
The extra pair of eyes may be the evolutionary precursors to the pineal complex in later vertebrates β represented in modern forms by the pineal gland and the parietal eye.

Hagfish!

Hagfish!
Excellent choice!!
Have you seen a hagfish (Order: Myxiniformes)?
I have now
Yes, in photos/videos
Yes, irl
I'm not sure
Photos are of an Atlantic hagfish, and a sixgill hagfish, respectively. Hagfish are the only known animals to have a skull while not having a vertebral column. They are one of two living groups of jawless fish, the other being lampreys.
I like this phenomenon
and now, for the next time period, the Ordovician! ------ y ahora, el siguiente periodo, el Ordovicico!

Pacific Lamprey Conservation
After hiding under the substrate at a fish research center for nearly 7 years as larvae, Pacific lamprey EMERGED as juveniles with eyes and a suction disk mouth! These fish, which are of Tribal and ecological importance, are now ready for their journey out to sea! The Abernathy Fish Technology Center in Washington worked in collaboration with the Yakama Nation, the Confederated Tribes of the Umatilla Indian Reservation and the Chelan County Public Utility District to conduct this research to further understand and conserve Pacific lamprey. This is a rare accomplishment to have Pacific lamprey reared and transformed in a captive setting.

today's vertebrate.........geotria australis
geotria australis has a big beautiful pouch near his mouth, which he uses for storing his fancy rock collection! he's got many kinds of rocks in there, and it would take me many lifetimes to list even a fraction of them!
don't worry though, the comical amount of rocks inside his sack doesn't impede him from enjoying his other hobbies in any way
shlompiness rating: sack

what an animal. this might be the animal of all time
i think it's safe to say that this 1920s Eptatretus cirrhatus drawing by Louis Thomas Griffin gives me psychic damage. the longer i look at it the more unease i feel.
so of course i want to keep it in my blog
